Hi Markus

Just a few thoughts of mine:

FQDN entries speed up queries because you only have to process one 
result instead of two (one for example.com and one for the 
corresponding www entry). Having two entries is a mistake also made 
by the bind ldap developer in his latest scheme. The negative effects 
simply outweights the positive ones.

This was a design decision which requires some work to change it now, 
but I would also prefer if the priority value would be in the content 
entry. This would save me the code to do it myself in the ldap 

The only other record type I've seen a priority value so far is in the 
SRV record.

I think most of the people wouldn't understand the nameing scheme if 
it would be changed to RDATA and PREFERENCES, so it isn't something I 
would consider.
